# deepEqual
> Test for deep equality between two values.
## Usage
```javascript
var deepEqual = require( '@stdlib/assert/deep-equal' );
```
#### deepEqual( a, b )
Returns a `boolean` indicating if `a` is deep equal to `b`.
```javascript
var bool = deepEqual( [ 1, 2, 3 ], [ 1, 2, 3 ] );
// returns true
bool = deepEqual( [ 1, 2, 3 ], [ 1, 2, '3' ] );
// returns false
bool = deepEqual( { 'a': 2 }, { 'a': [ 2 ] } );
// returns false
```
## Notes
- The function uses strict equality checks (`===`) and does not perform any type coercion.
- When given two objects, only enumerable own properties are recursively compared.
## Examples
```javascript
var deepEqual = require( '@stdlib/assert/deep-equal' );
var bool;
var a;
var b;
a = [ true, false, true ];
b = [ true, false, true ];
bool = deepEqual( a, b );
// returns true
b.pop();
bool = deepEqual( a, b );
// returns false
a = { 'a': { 'b': { 'c': 'd' } } };
b = { 'a': { 'b': { 'c': 'd' } } };
bool = deepEqual( a, b );
// returns true
b.a.b.c = null;
bool = deepEqual( a, b );
// returns false
a = { 'a': [ { 'b': 0 }, { 'c': 1 } ] };
b = { 'a': [ { 'b': 0 }, { 'c': 1 } ] };
bool = deepEqual( a, b );
// returns true
b = { 'a': [ { 'b': [ 0 ] }, { 'c': '1' } ] };
bool = deepEqual( a, b );
// returns false
```
